F36A060F0BD857F8B278533F251D1453.taxon	diagnosis	Diagnosis. Begonia fangchengensis mostly resembles B. rotundilimba in its elliptic leaf blade, palmate veins, dichasial cyme, three styles, axile placentation, and unequally 3 - winged capsule. However, there are creeping rhizome, pilose stipule, red and densely pilose petiole, pubescent leaf blade and pilose inflorescence bract, sparsely pilose ovary and the zygomorphic androecium in B. fangchengensis. These characters differ from the erect stem at anthesis, the green and densely villous petiole, the glabrous stipule, leaf blade, inflorescence bract, ovary and actinomorphic androecium in B. rotundilimba.	en	Hu, Ping-Ting, Huang, Yu-Ni, Zhang, Meng-Ni, Chen, Bi-Xuan, Huang, Shu-Shu, Li, Ren-Kun, Wang, Wen-Guang, Feng, Xin-Xin (2024): A new species in Begonia sect.
